ABS Light: Description and Operation

The ANTI-LOCK warning lamp is normally on until the Anti-Lock Brake Control Module (ABCM) completes its self tests and turns the lamp off. The ANTI-LOCK warning lamp is illuminated when the ABCM detects a condition which results in a shutdown of Anti-Lock function.
Display of the ANTI-LOCK lamp without the red BRAKE warning lamp indicates only that Anti-Lock function has been disabled. Power assisted normal braking is unaffected.
